Great news, because that's what I am building. M73 bottom end, M70 heads with Schrick cams.
Can I order the chips from you now?

yes, you can. Just send me an email to info@wokke.de
The cams are probably the most expensive single item here. Maybe we can do a group buy?

So, where are all these M73's residing that will need to be harvested?
1993 850Ci.....18 years & 165,000 miles and counting!
I have the m73 with 60k miles, but now need the "S" Cams
Wokke, not so long ago, after wondering around the forum I've seen a chart you posted with M70 M73 S70 and Schrick Camshaft Specification.. I tried to find it again, but no luck..
... would you be able to post it again? please!!
I would really appreciate that!
.... Cam data comparison... "How hard can it be!?" To find a cam specs on bimmerforums!
Is there that much difference in the bottom end of an M73 to a M70? I realize the M73 has higher compression than an M70, but couldn't you just buy 10.5:1 compression pistons for an M70 and get the same result?

I would buy a set of Schrick cams.
Is there any markings on camshafts if it's schirck!?
I only own my 8 for a year, don't know if previous owner did anything to her.
There are markings on schrick cams you would be able to easily see it, its in between the lobes I believe. But chances of someone installing these cams is slim to none.

You can spend exponential amount on the top end. Just keep in mind, cams + a good valve job will already run you $2500 easily. So you have to think of what is your over all budget for this engine.
In my opinion you have to really control your budget because if it starts to creep up into supercharger territory then it's pointless....IMO
I totally agree. I know that sometimes performance cams can be too much for oem equipment. I didn't know if this was the case with schrick. What is the consensus about just placing these in existing stock heads without rebuilding them?

The pics are broken? Anywhere else I can see some of the work you did? Everyone makes it sound like it's one of a kind must see
Wolf - I am going to pull together a list of specific workarounds that are required from all these posts. But out of curiosity, do you have an approximate number of hours you would ballpark for a guy that has only done a top-end on an M70?

Are the m73TU motors eligible as a donor motor as well?
As I was looking, I noticed that designation as well. What is the difference? And can they be used?
